I posted on DF about this since the dev's read that regularly and usually reply there, but for the sake of providing some feedback here as well, here the main observations I have so far:
tons of customization options - I'm sure that's what most people like about it.
But I also ran into a few issues:
* Restoring apps was a bit a pain, didn't restore anything from market by itself, so I restored them via TiBu.
* My battery life seems to be taking a beating on 2.0. Went from fully charged (it was on the charger for a few hours) to 20% in a few hours with medium usage at best (Slayher 1Gz kernel, interactive, with SetCPU on it). That same kernel on other ROMs was giving me better battery life for sure, so that's a bit of a downer.
* Some of the apps you can install via sourcery magic didn't install at all for me (wireless tether for example).
* The modified contact app #2 doesn't show contact info for favorites, so I went to modified app #1 - which is less appealing to me, but it doesn't have that problem.
* The ROM comes with that app "iHear Network" - not sure why one would include this type of app with a ROM, but whatever. I don't have any need for this app, but there is no option to un-install it in Sourcery Magic, nor can I uninstall it through app manager...
I also don't particularly like the scrolling "sourcery" on the lockscreen, but that's just a matter of personal preference I suppose.
